Toronto-based All Things Cling enhances promotional materials — such as postcards, banners or invitations — with Cling-rite, an electronically charged, printed polypropylene film with an embedded static charge. The material sticks to almost any clean surface for easily positioned posters. Once peeled from its protective backing, Cling-rite will stick to the desired surface again and again. The company also provides Clingers, a low-tack adhesive that does not leave a residue. For more information, call 416/630-3131, or visit www.clingers.com.
